poses set forth.

A drawing illustrating an embodiment of the invention is hereto attached, the following views being shown:

Fig. 3, is a view in end elevation, of a slightly modified form and looking at the front end of the car;

Y In these views, 1 designates a car ing a door 2, swingingly mounted at its upper edge on one end of the car, the other end 3, being an integral portion of the'body. The door 2, is provided with keepers 4, extending outwardly beyond the plane of the sides of the car and adapted to be embraced by and securely locked with a unitary loopshaped locking-member 5, which member is pivotally and slidably mounted so that it may be brought into position to engage the keeper 4, and then swung down to lock the parts together, the weight of a portion of the latch acting to maintain the parts locked until operated by simply turning up the loop and moving it back from the lug; 'This body hav- 7 loop-shaped locking-member 5 Ii'orm'sithe subjeot' matter of a separate application, filed Oct. 13, 1923, Serial No. 668450.

this is in shape or 2 loop-of substantial 1's antended to be ;:engaged by and held against the inside of the front end of the car by the contents of the body. In other words, when the body is filled up above the lower portion of the bail, the bail will bear against and beheld in engagement with the inside of the front of the car, and will,

through link 8 and its connection with the swinging door,hold the door in closed'posi-' tion until the car is tilted in the dumping operation. Thetilting will remove the contents from the bail and permit the outward swinging of the door on its hinges. The device constitutes a verysimple and effective means of permitting dumping at the same 1 time maintaining the door in closed position until the car has been actually tilted.

In the formshown in Figs. 3 and 4, there I r is a slightly modified bail construction wherein a hook I?) is substituted for the looped bail shown in Fig. 2, the hooked por-- tion being adapted to pass through an open.

ing 1% in the front of the car and be en gaged by a latch 15, pivotally mounted on a plate l6 secured to the front of the car. This provides a simple and eflicient auxiliary locking device or one which may be used independently of the, looped member 12 previously described." 1

While the invention has been described in connectionwith the present embodiment, it

will be understoodthat I do not wish to be limited to the precise form of this disclosure, as many changes in the structure and ;ar-,

rangenient of the partsare considered Within the scope of the invention asset forth in the claims. 7

What I claim is: u 1. A dumping appliance comprising a body"; a door mounted for swinging move-- ment thereon; instrumentality disposed on the exterior of the body and connected with the door and including a downwardly-extending member Within'the body and adapti f ed to bear against the inside of the front end of the car and be engaged by contents of the body to maintain the door in closed position.-

2. A dumping appliance comprising a body; a door mounted for swinging movement thereon; instrumentality disposed' on theexterior of the body and connected with the door and. including a downwardly-ex tending member within the body and adapted to bear against the inside of the front end of the car and be engaged by contents of the body to maintain the door in closed.

' position, and means associated with the door for locking the door to the body;

- 3. As dumping appliance comprising a body; a'door mounted for swinging movement thereon; instrumentality disposed on the exteriorof the body and connected with the door and including a downwardly-ex-v tending member within the body and adapted to bear against the inside of the front end of the car and be engaged by contents of the body to maintain the door in closed 7 position, and means for locking the contentsengaging member to a portionof the body.

l. A -dumping appliance comprising a body; a door mounted for swinging movement thereon; instrumentality Connected with the [door and including a member adaptedto be engaged by contents of the body to maintain the door in closed position, means for locking the contents-engaging member to a portion ofthe body, said means including a bail provided with a hook adapted to pass through an opening provided in a portion of the'body; and a locking member operatively associated therewith adapted to be engaged by contents of the body andgthrough the instrumentality of the arm and connecting member, to hold the door in closed position until the car is tilted. v i

In testimony whereof I aflix'my signature.
